Dear all,

Here i wanted to go from basic. I need basic steps to calculate or choose proper wormgear & motor for solar tracking application.

If someone can guide me necessary formula & parameter required to calculate the worm gear box . i have already discuss this topic earlier but not posted in in right thread & i didn't get response

**calculation formula required:**
1) torque Vs speed relation for motor & worm gear
2) torque Vs load for motor & worm gear
3) Input power & output power for motor & worm gear
4)turns ratio relationship with motor & worm gear.

I know these are basic question but some tracker design taking kinematic calculation for this. http://www.roymech.co.uk/Useful_Tables/Drive/Worm_Gears.html

so if some one can guide with proper resource it will be more help full.
